Abstract
- Sunitinib, a multi-targeted tyrosine kinase inhibitor, is used for the treatment of renal cell carcinoma and gastrointestinal stromal tumors. Many adverse effects associated with sunitinib, including hypertension, proteinuria, and thrombotic microangiopathy, have been reported; however, the other forms of glomerulonephritis are very rare. We report a case of biopsy-confirmed immune complex glomerulonephritis in a patient with a gastrointestinal tumor who received sunitinib treatment. The proteinuria subsided partially after sunitinib was discontinued, but when the drug was reintroduced, it recurred.
